‘He picked up a stick and struck the defendant. That startled the horse, causing it to run off, dragging the defendant with it.’ Chamberlin’s solicitor, Alex Bousfield, said: ‘Mr Chamberlin cannot explain what happened. He didn’t know how to account for that behaviour.’

Chamberlin, from Middlesbrough, admitted outraging public decency by committing a lewd act and was handed a 24-month community order.

He was also given a sexual offences prevention order – which means he cannot have unsupervised contact with anyone under 18 and is banned from owning or being around animals unsupervised.

Chairman of the bench John Meredith said Chamberlin caused stress to the ‘owner and the animal itself’.
